TRACK-SANDER.

Specification of Letters Patent.

Patented March 9, 1909.

To all whom it may concern:

- Be it known that I, CHARLES W. G. KING, a citizen of the United Statesof America, rcsiding in the city and county of Philadelphia, in theState of Pennsylvania, have invented a certain and useful Improvement in'lracleSanders, of which the following is a true and exact description,reference being had to the accompanying drawings, which form a partthereof.

The present invention relates to sanding devices of the kind employed onvehicles and particularly on railway locomotives for feeding sand ontothe trackway for the vehicle wheels to prevent slipping.

The invention relates to that type of sander in which the sand may passfreely from the sand dome or other sand reservoir into a small chamberin the sanding device proper from which it is ejected as needed by theac tion of an air or steam blast, the walls of said chamber being soformed and arranged that the chamber forms a trap from which the sandwill not flow when the blast is shut off.

The object of the invention is to provide an improved sander of thegeneral kind described which will be simple and durable in constructionand reliable in operation, and particularly to provide a sander in whichthe nozzle through which the blast is introduced into the trap chamberis so located and arranged that it will not be injured by the sand blastwhen the latter is in operation and in which the interior of the sandingdevice may be readily opened for inspection, adjustment or repair, andin which the various passages apt to clog up and particularly thepassage leading to the trap from the sand dome or other sand reservoirmay be readily cleaned out when necessary.

The various features of novelty which characterize my invention arepointed out with particularity in the claims annexed to and forming apart of this specification. For a better understanding of the inventionhowever and the advantages possessed by it reference may be had to theaccompanying drawings and descriptive matter in which I have illustratedand described one of the forms in which the invention may be embodied.

Of the drawings: Figure l is a plan of the sander and a portion of thesand dome or reservoir, and Fig. 2 is a sectional elevation on the line22 of Fig. 1.

In the construction illustrated, A represents the body of the sanderwhich is preferably provided with a flange B for attachment to the wallof the sand dome C or other sand reservoir. The body A has a portion Awhich extends into the sand reservoir and the body is formed with theelongated trap chamber or passage D which is nearly horizontal but ispreferably inclined to the horizontal at about the small angle shown sothat the outer end of passage D is above the inner end of the pas sage.At the inner end of the passage D a blast nozzle is provided. In theform shown the nozzle E is formed in a nozzle member E threaded into thesocket E formed in the member A. The socket E communicates with a curvedpassage F formed in the member A and opening without the flange B at Fwhere a suitable air or steam supply pipe may be connected. At its outerend the passage or chamber D joins the downwardly extending dischargepassage G which leads through suitable pipe connections to the trackway.A cap or separable portion H of the body A is in line with chamber D andpassage G is removably secured against its seat H by bolts H fi H is awasher employed to insure a tight The member A is provided with alateral sand outlet passage T which is open at one end to the interiorof the sand reservoir and at the other end to the passage D, at anappreciable distance in front of the nozzle E. The passage I is inclinedto the passage D so that the former passage may be readily cleaned outby a straight stick or other de vice inserted through the outer end ofchamber D when the cap H is removed. To illustrate this, I haveindicated in the drawing, the point Y, where the center line X of thepassage T intersects the plane of the seat H The passage 1, which isrelatively short, is upwardly inclined from its sand reservoir and toits end to the passage or chamber D. The nozzle member E may be readilyremoved and replaced or adjusted by a tool through the outer end ofpassage D when cap H is removed.

It is obvious that the construction disclosed, on account of the fewnumber of parts and the simplicity of their construction, possessesexcellent mechanical propvibration, will pile up in the chamber D toabout the extent indicated at Z. When the sanding device is subjected tomuch vibration, the lower end of passage D may fill up wholly or partlywith sand, but the inclination of passage D is, or may be readilymade,rsuch as to prevent any sand from shaking down into passage G andbeing wasted. As soon as the blast from nozzle ll isstarted-the portionof the chamber D, to the rear of passage I, is wholly or largely clearedof sand. In consequence, the nozzle member is not subject to the cuttingaction of the sand blast as is the case when the nozzle is practicallyburied in sand while the blast is going as is the case with the sandingdevice heretofore in most common use.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A sanding device comprising in combination with a sand reservoir, .abody extending into said reservoir and formed with a chamber serving asa sand trap through the outer end of which the sand may be blown andwith a lateral sand inlet passage open at one end to said reservoir andat the other end to said chamber :at an appreciable .distance in frontof the inner end of said chamber, said body being provided with a blastnozzle located at the inner end of said chamber.

2. A sanding device comprising in combination with a sand reservoir, abody extending into said reservoir and formed with a chamber serving asa sand trap through. the

outer end of which the sand may be blown and with a lateral sand inletpassage open at one end to said reservoir and at the other end to saidchamber at an appreciable distance in front of the inner end of saidchamber, said body being provided with a blast nozzle, and a removablecap at the outer end of said chamber, said passage being inclined tosaid chamber to permit the passage to be cleaned through the outer endof said chanr her when said cap is removed.

3. A sanding device comprising a body adapted to be removably secured toa sand reservoir with a portion projecting into the reservoir and formedwith an elongated chamber slightly inclined downward from the horizontalfrom its outer and discharge end to its inner end, said body'beingprovided at its inner end with a blast nozzle and being formed with alateral passage open at one end to said reservoir and open at the otherend to said chamber at an appreciable distance in front of theblastnozzle.

4. A sanding device comprising a body A adapted to be removably securedto a sand reservoir with a portion A projecting into the reservoir andformed with an elongated chamber D, provided at its inner end with ablast nozzle E and opening at its outer end to a downwardly extendingdischarge passage Grand having a removable cap H at the junction of thepassage G and chamber D, said body being also formed with a lateralpassage I open at one end to the sand reservoir and at its other end tothe chamber D at an appreciable distance in front of the nozzle E andbeing inclined to said chamber so that it may be readily cleaned by astick inserted through the outer end of said chamber D when said cap His removed;
